Mixing & Mastering Engineers, Producers & Songwriters who worked with Danny O'Callaghan

Tasteful, dynamic drum tracks with a vintage vibe recorded at The Factory Studios, just outside London, UK. Songs featuring my drums tracked remotely have been mixed and mastered at top facilities including Abbey Road and Metropolis Studios, and have gone on to receive BBC radio airplay and over 3 million streams.
